    • Simple, Effective, and Made Right
Finally found an affordable pillow protector that does exactly what it needs to do. The 100% cotton fabric is the real standout here. It breathes well overnight, feels soft against skin, and doesn't have that crinkly, synthetic feel that cheaper protectors are known for. The zipper is smooth, snag-free, and easy to operate with one hand. Most importantly, it just works. Pillow is protected, the cover stays in place, and it washes and dries without shrinking or pilling. No fuss. ... show more

    • Excellent quality and value for money
I bought a pair of these Amazon Pillow Protectors, and I must say I was pleasantly surprised. The quality of this Pillow Protector is excellent. It is made of 100% cotton, so it is very comfortable and breathable to sleep on under the pillowcase. Additionally, the quality of the fabric, the zipper, and the stitching is top notch, so it will last a long time. Easily washable. Excellent value for the money. Highly recommended. ... show more

    • Great Product!!
Sometimes Amazon Basics can be hit or miss, but I must say I like these. Nicely made, great size, you do not have to feel like you are stuffing a sausage into a casing, fabric is 100%cotton, and I do expect some shrinkage, but these are oversized enough you will barely notice it. They are perfect to use as a zipper pillow case or a cover for your pillow which will have a regular pillow case. I bought 4 sets, and for the price you cannot go wrong. Amazon did a good job on this one. For my purposes, they will work well. Nice weight to the fabric, not thin. Zipper in a nice place, They are bright white and the size is perfect (hard to find). As for sleeping, no noise, and heat or cool, they are cotton. Cotton breathes, gets softer each time it is washed, and I think they will last some time. They are covers for my feather and down pillows. I am quite happy with them. ... show more

    • Very nice pillowcovers!
Very nice soft cotton pillowcase covers with hidden zippers. True to size, they fit my 19X29 queen pillows perfectly with a little room to spare for pulling them on easily over the pillows. The covers wash well and can be used just fine without ironing. Made of quality cotton, they neither grab at the pillowcase put on over them nor do they slip inside the pillowcase. An excellent solution for keeping pillows fresh and clean, and worth the money.* ... show more

    • Exactly what I needed at a reasonable price
I specifically wanted cotton because I tend to get really warm at night and polyester just does not work for me. These have been a great switch. They are a good size and fit my king pillows well. The zipper is a nice bonus and keeps everything in place. They have held up well in the wash so far with no issues. I do iron them because I like that crisp feel, and they come out looking really nice. Overall, great value for the price and exactly what I needed. ... show more
